I have replaced most hoses on engine and got around to ordering brake booster and manifold fuel vacuum hoses. After 1 month of trying to find one Tasca says that none exist and there is no restock date. Hose has built in check valve so can't be replaced with straight tubing. Might go to junk yard get an old one and cut the check valve out make a new one. This hose runs right on top of the engine from intake manifold to brake booster and is made from the same quality thermoplastic as all the other cheap crappy plastic engine parts.
